I have a DJI MINI 2, it has a great camera on a gimble weighs less than 250 grams so no license or registration required. I use it to film video and it shoots beautiful video but if one wanted to put drone video on the internet, even on YouTube you need to license your drone.
Actually, you need to get a part 107 license for yourself if you want to post videos on YouTube. If you are a private pilot it is simpler you can take a free online test from the FAA and then get your flight instructor to sign off in your logbook. And yes, you need to spend $5 to register your drone also.
Putting drone videos on YouTube is risky business anyway. Anyone who sees it can spot something that you have done wrong and then report you to the FAA. Even if it is complete BS you might have to hire an attorney.
Yes, they are very good drones, and they can also use 3rd party software that can add automation and other features. You might want to check if litchi has any features that you might be interested in.
I also use dronelink and there are other 3rd party apps as well.

Litchi is the more versatile and cheaper app.
